The world's toughest running events revealed

Forget the Marathon des Sables, these beasts of races are almost guaranteed to break you
Take on the world's toughest foot races

You’ve done the London Marathon. Sure, it was hard, but you wanted a tougher running challenge to set your sights on. You searched for something harder, a race with a bit of elevation. Snowdon Marathon looked perfect, so you did it and got round.

So what’s next? How do you push yourself to the limit of human endurance? The point where your body and mind begin to unravel? You, my friend, are ready to take on one of the world’s toughest races. Here, we’ve ranked them in order of the chances of you finishing the race – most likely to least likely.

Remember, some people actually enjoy doing these.

Everest Marathon

Take on the world's toughest running events

For those who aren’t fans of oxygen, this starts at an altitude of 17,500ft. Racers need at least two weeks to acclimatise to the oxygen-depleted air – and trek to the start – and you’ll be glad to know the route takes you largely downhill rather than up.

That doesn't mean it’s lacking in climbs though – and at this height they feel five times as hard. And ditch that dream of a podium place, as the top 10 are usually local Nepalese Sherpas.

Finisher's quote: “There’s an area on the way to Gorak Shep which is known for rockfall, so I was really keen to get past this quickly – and avoid getting hit by a rock.” Laura Jones

Where: Everest Base Camp

When: 29 May 2020

Distance: 37 miles

Elevation: 5,577ft

Per cent of non-finishers: Most runners finish, but if you miss the 4pm cut-off you have to restart at 6am with a 3-hour time penalty

Ultra Trail of the Gobi

One stage, 273 miles across the inhospitable Gobi desert, 149 hours to complete it. It’s based on the journey undertaken by the 7th century Buddhist monk Xuanzang, which, admittedly, took him a few years rather than less than a week. He made a note at the time that “when it is hot, the heat sears you like a flame; when it is cold, the wind cuts your flesh like a knife”.

Finisher's quote: “Ultra Gobi is the most difficult race I ever took part in. It made me learn a lot about myself, especially how to handle pain.” Clement Dumont

Where: Gansu Province, China

When: August 2020

Distance: 273 miles

Elevation: The official site says “the race does not have much elevation gain/loss”. Make of that what you will…

Badwater 135

A generous cut-off time of 60 hours might make you think this is an easy road race. That is until you check out the temperatures you’ll be experiencing out on the course. The race starts in the Badwater Basin, the lowest point in the US, 280ft below sea level. Then it climbs and climbs, winding its way up to Mount Whitney at 8,500ft. Again, straightforward enough until you add in the fact that you are essentially running in a furnace – temperatures can reach a sole-melting 50C (122F).

Finisher's quote: “Every time you inhaled the air was so hot that it seared your parched throat and stung your lungs.” Scott Jurek

Where: Death Valley, California, US

When: July 2020

Distance: 135 miles

Elevation: 14,600ft

The Ultra Trail Mont Blanc

Most runners have heard of the UTMB, one of Europe’s biggest and toughest ultramarathons. Every year, 2,300 sufferfest fans gather in Chamonix’s town square as Vangelis’s Conquest of Paradise plays before they head out for a 105-mile ‘jaunt’ around Mont Blanc. With 46 hours in which to complete it, runners pass through rapidly changing weather, ankle-twisting terrain and sleep deprivation – the perfect recipe for a DNF.

Finisher's quote: “[I’m ascending] one of the hardest climbs of the race. But I’m past being defeated. My whole existence is focused on just moving. This is the pain cave, this is where ultra runners look to go, to dig, hoping to find what they are made of.” Adharanand Finn

Where: Chamonix, France

When: 30 August 2019

Distance: 105 miles

Elevation: 32,808ft

Per cent of non-finishers: 31%

Spartathlon

Another race based on an epic journey, this time Pheidippides’ fatal trek to deliver a message asking the Spartans to help the Greek army. This is brutal for many reasons (aside from the distance) – the 75 checkpoints have strict, and challenging, deadlines you have to reach them by, which can make your pacing go out the window as you crash and burn before the halfway point. And that’s before you hit the calf-shredding 3,500ft climb up Mount Sangas at 100 miles.

Finisher's quote: [At mile 100] “Running is no longer an option. It’s not a pain thing; I can take pain. It’s an impossibility thing. I am simply not able to run anymore. And still more than a marathon left to go.” Vassos Alexander

Where: Athens, Greece

When: 27-28 September

Distance: 153 miles

Elevation: 3,937ft

Per cent of non-finishers: 38%

The Spine Race

It’s difficult to dispute the Spine’s billing as ‘Britain’s most brutal race’. The route, heading north along the Pennine Way, is hard enough, but as it takes place in the middle of January you have Britain’s winter weather to contend with too. And it’s non-stop, so you’re trying to grab an hour of sleep when you can. Most runners who quit the race do so because they have succumbed to the effects of hypothermia.

Finisher's quote: “It was the first time I’ve been to a race briefing where you could hear a pin drop. The competitors didn’t utter a sound as we sat and listened to the safety aspects of the race, signs of hypothermia and actually how potentially dangerous this race could be.” Mimi Anderson

Where: Edale, Peak District, UK

When: 12-19 January 2020

Distance: 268 miles

Elevation: 36,792ft

Per cent of non-finishers: 42%

6633 Arctic Ultra

For this one, you’re above the Arctic Circle, meaning temperatures can drop to -40C, you have to drag a 30kg sled loaded with your belongings and winds can hit 30mph, leaving you frozen and alone. Aside from frostbite, you’re out there on the ice from 3am until midnight, on your own, for a week and a half, which means that for many the biggest battle is with your mind.

Finisher's quote: “The flat part is the part that generates the most abandons, as people just can’t take the lack of direction. People have difficulty keeping balance. Everything is white so you don’t have any points of reference – it is easy to fall over.” Tiberiu Uşeriu

Where: Eagle Plains, Yukon

When: March 2020

Distance: 383 miles

Elevation: 12,887ft

Tor des Géants

Here’s the stats: 25 peaks over 2,000m, 205 miles, 70,880ft of elevation gain. Feel your quads recoil at the thought? This is a toughie, no question. The name of the race translates as ‘Tour of the Giants’, as you will be circumnavigating Mont Blanc, the Matterhorn and Monte Rosa through almost every type of weather, from baking heat to zero-visibility hailstorms.

It’s a non-stop race, which means you have six days/150 hours to get round, and you choose when to rest and sleep. Last year there were so many foot injuries and blisters that the medical team needed three times more bandages than they had estimated.

Finisher's quote: “The climbs just seemed to go on and on and on and just when I thought I was nearing the top I’d spot a headtorch in the distance heading away from the col in a different, much longer and higher direction.” Paul Tierney

Where: Courmayeur, Italy

When: 8-15 September 2019

Distance: 205 miles

Elevation: 70,880ft

Per cent of non-finishers: 60%

Montane Yukon Arctic Ultra

The Montane Yukon Arctic Ultra ramps things up a notch from the 6633 Arctic Ultra, pushing the distance to 430 miles, meaning it will take at least nine days to finish. You can opt to travel on skis or bike, but most go for foot, and frostbite is the biggest danger out there. Also, expect to hallucinate – competitors often report seeing monsters in the snow and ghostly aid stations.

Finisher's quote: "The last night was dark, literally and figuratively. If you had asked me my name I would not have remembered it." Christof Teuscher

Where: Whitehorse, Canada

When: 30 January-7 February

Distance: 430 miles

Elevation: Unknown, but the highest point is 4,049ft

Barkley Marathons

The Barkley Marathons has reduced some of the world’s most hardened ultrarunners to shells of their former selves curled up in the foetal position on the freezing ground. Race organiser Lazarus ‘Laz’ Lake likes to make it challenging and, as such, this means only 15 runners have completed the full five laps within the designated 60-hour limit.

Finisher's quote: “The Barkley will find your weaknesses, and it will exploit them.” John Kelly

Where: Wartburg, Tennessee

When: Last weekend in April, 2020

Distance: Five loops of the course is approx 130 miles, but likely to be significantly more

Elevation: Approx 60,000ft

Per cent of non-finishers: No finishers in 2019

Enter: It’s a secret
